Measurement of the Attenuation Coefficient in Fresh Water Using the Adjacent Frame Difference Method
Photonics, 2022 The attenuation coefficient of a water body is one of the important factors for describing its features. However, its remote measurement in real time is still a challenge.

Theoretical analysis of backscattering in hollow-core antiresonant fibers
APL Photonics, 2021 We present a theoretical analysis into the fundamental physical mechanisms contributing to backscattering in hollow-core antiresonant fibers. We consider Rayleigh scattering originating from the hollow regions of the fiber, which may be filled with gases,

A Fast Scattering Model for C-Band Data Simulation in Forest Scenarios
IEEE Access, 2022 Synthetic aperture radar (SAR) data simulation of forest canopies is a common method used to study the interaction between radar and forests. The forest canopy contains a large number of small leaves, which require many computing resources to calculate ...

Soil Moisture Retrieval from the Chinese GF-3 Satellite and Optical Data over Agricultural Fields
Sensors, 2018 Timely and accurate soil moisture information is of great importance in agricultural monitoring. The Gaofen-3 (GF-3) satellite, the first C-band multi-polarization synthetic-aperture radar (SAR) satellite in China, provides valuable data sources for soil

A Modified Two-scale Microwave Scattering Model for a Dielectric Randomly Rough Surface(in English)
Leida xuebao, 2015 In this paper, we present a Modified Two-Scale Microwave (MTSM) scattering model to describe the scattering coefficient of naturally rough surfaces. The surface roughness is assumed to be Gaussian in the proposed model so that the surface height z(x, y ...
